The arms 16 carrythe half clamp sections 27 which embrace the rearmost section of thetube 17. These rear clamp sections 17 have perforated lugs 28 adapted tomate with similar perforated lugs 29 on the forward complemental clampsec'- tions 30 which embrace the forward members of the tube. Bytightening the bolts 31, which pass through the perforated lugs, orloosening such bolts, the width of the slots 25 and 26 and the degree ofcompression of the steel coil spring 18 may be regulated.

The tube may or may not be provided with a lining of rrubber or fiberbetween the tube and the Spring 18, whereby to stop any rattling of thespring in the tube incident to the vibration of the vehicle.

Referring to Figures to 10, inclusive, the adaptability of the inventionfor use as a bumper bar is shown, it being understood that the device isenlarged and strengthenedto suit i't to this purpose. Such a bumper baris shown at 32, being preferably cylindrical in general contour andbeing hollow to receivethe strong steel coil spring 33 which may bespaced from the interior 4 of the cylindrical bumper bar 32 by means ofa rubber, liber or other lining 34. This lining may be formed in strips,as shown in Figure 8.

.The bumper bar 32 is provided with removable endcaps or horns 35.Within these horns, the ends of the tube carry disks '36 removably heldin place by set screws 37, or other appropriate means; The disksareprovided with threaded openings to receive therethrough the screw shafts38. The inner Aends of the screw shafts 38v carryy disks 39 which slideback and forth, either compress- Y in or releasing the coil spring 33.

he bumper bar 32 is provided with a `Series of upper perfor-ations V40and 'with a 'series of lower perforations 41 disposed in registry withthe upper perforations, wherebv to receive the flag staffs and theprongs of the yletters or symbols, as shown in Figures 5 'and 7.

vThe bumper bar is held upon the vehicle n by the brackets 42 in theordinary way f Referring to Figure 9, one of the etters 22 is shownhaving two prongs 21 spaced apart and provided with lower pointed endsto facilitate the prying apart ofthe helices of the spring andy for theentrance of the prongs between such convolutions.

In Figure 10, a single prong 21is shown of a similar construction, andit will be understood that one or more prongs may be carried by theletters or by the s mbols used.

It will also be understood tiat ay small fory the purpose of floodlighting equipped with similar prongs may be held yin the device andilluminate the display.

In the use ofthe device, in Figure 1, I have shown two flags set in thedevice 'at opposite sides of the elks insignia and initial letters. Aflood light might also be arranged to play upon this display at night.It will be understood that the prongs of the letters and symbols and thestaffs of the flag extend through the upper and lower slots and throughthe convolutions of the spring, and that great stability is given to thedisplay devices by the engagement of such spring and staffs with theside walls of both upper and lower slots, and in this way, 'the displayis adapted to withstand that considerable pressure encountered inautomobile driving.

l, A similarfsituation exists in the modified form of the device shownin Figures 5 to 10, the prongs of the letters and the staffs 'of theflag extending through both upper and lower series of perforations and41,

yand the devices also being held against lateral movement by the sidewalls of such perforations, so that the dis 'lay is constantlymaintained in its origina attractive position and resists all jarringout of place.

- It will be obvious that many changes in the construction, combinationand arrangement of parts could be made, which could be used Withoutdeparting from the spirit of my invention, and I do not mean to limitthe invention to such details, except as particularly pointed out in theclaims.

Having thus described my invention, what I claim anddesire to secure byLetters Patent of the United States isz- 1. An improved display devicecomprising a coil spring, two semi-cylindrical tube sections assembledon said coil spring and means for compressing the sections selectivelyupon said spring.

2. An improved display device comprising a horizontally disposed tubehaving openings in its upper and lower portions. means for holding thesame substantially ytransversely of a vehicle, a coil spring mounted insaid tube, lining material between said coil spring andthe tube, andmeans for adjusting the tension of the coil spring.

3. An improved display device comprising a tube having openings in itsupper and lower portion, a coil springmounted in said tube, means in theends of the tube for selectively compressing the coil spring, and end`caps on the tube for concealing the ad` justing means.
